This concludes the chapter on XPages mobile application development. So what does the future hold? Responsive web design is emerging as a new approach for building web interfaces with an optimal viewing experience across mobile and desktop browsers and beyond. Bootstrap for XPages is already available as an extension Library, and this provides functionality to allow you to build responsive user interfaces. For more information on using Bootstrap with XPages, visit: http://bootstrap4xpages.com/. One UI is expected to also evolve in this direction. So in the future (if you are not already there) the lines between developing for the desktop and developing for mobile will blur, and the techniques you will use now for building Mobile XPages applications will become the mainstream techniques you will use.
